There are four of us (all adults and fit) planning on spending 4 days in the Lake District in September. We will be travelling down from and then returning to Edinburgh. We have accommodation booked for 4 nights just outside Ambleside. This will be our only trip to the lakes and would like recommendations that will give us a good overview of what the lakes have to offer. We are happy to drive around to see attractions or get to recommended walks but would prefer to limit this as we will be doing a fair amount of driving during our UK trip anyway. Any recommendations that are farther north of Ambleside could be visited on the way down or back up to Edinburgh. Many thanks.
